[Myth_buster_1]

Uh what is your problem haan? Have they exploited you in some way or what? What is part of history? If you have some FACTS present it or don't brag with some 8 year old news item.

listen mate (Mod edit)! do i have to prove you the fact that the nazi lost WWII with 2009 articals but i can not post some 60 year old news because they are out dated? are you clearly a retard? The artical that i posted is infact of your rtd Air chief words!

Answer to a Press - Dr. Kota

Why did it take 16 long years for the first LCA flight to happen?

The last fighter we developed was the HF 24 Marut (Hindustan Fighter) in 1961. There was a gap of 40 years. In the area of fighter aircraft, we have to run if you want to stay where you are. When the LCA project came into being, we had to build facilities, train people, develop technologies, develop components, develop equipment, integrate the whole thing. And the technologies that we have deployed state- of-the-art. The amount of testing that we had to do was enormously high. Not only were the designers new, but the inspection team and airworthiness team also had to learn the technology. The test pilot also had to undergo the process of learning. The whole project had to be done from scratch.

Building of the F-22 aircraft began in 1980 and it flew first in 1997 - after 17 years. The Eurofighter was to make its maiden flight in 1990, but it flew in 1994. The UK, Germany, Italy and Spain have been involved with the EFA. Why is the media mum on this aspect? Western nations are continually working on prototypes and have more time, Considering their technology. As for the joint strike fighter (of the US)-it is only being test-flown and it is estimated that it will be ready in 2004. They still have to work on it. The joint strike fighter has been discussed for more than a decade - since 1982. In a complex programme, such as one involving aircraft, so many technologies are being developed - 15 years is not a long time. But moving ahead should be faster - the aircraft can enter into service in 2005 or 2007, but decisions are needed to enter production.

How do the other countries manage ?

The European fighter aircraft has been developed by four European countries - UK, Germany, Italy and France. They were to have their first flight in 1990, but they actually flew only in 1994. That means with four advanced nations working together, they took four years more than what they predicted. In the case of LCA, we planned to fly in December 1996, but we flew only in January 2001. About four years of delay. The Europeans did not have any US sanctions. And all these countries had a continuous stream of aircraft being developed. So I don't think the delay in the LCA's first flight is anything unusual. The US conceived the F-22 as early as 1980. The first prototype flew in 1997- after 17 years. It is not unusual for high technology programmes to take time.

What is the significance of the LCA ?

The LCA has been designed to replace the MiG series of aircraft. This is a very light aircraft, supersonic, multi-role and has very advanced technologies, comparable to the best available in the world today. The LCA has indigenous content of more than 70 percent. So there are huge job opportunities. Also, critical technologies such as advanced composites, digital fly-by-wire, the all-digital cockpit, digital avionics, utility management systems and a host of other technologies have been developed.

These technologies not only make the LCA an excellent fighter, but are available for all other programmes. The spin-offs are many. For example, more than 100 equipments developed for the LCA have already found their place in the Intermediate Jet Trainer (IJT) project that has been sanctioned recently by the IAF to HAL. Our software is already being used for development of the composite parts for the development of the Airbus aircraft. More than 300 industries in India have participated. So it is not merely that an aircraft has been test flown, but the technologies and capabilities also are now ready. This is very important and critical for strategic and academic aspects of the country.

dr kota

these are more than enough for your mudslinging questions

there is something called as product design and as the product gets smaller lesser things u can stuff and keeping the functionality of the product to a respectable level becomes difficult .

for example ever tried building a mere scale model in 1:72 and 1:32 with the same detail

one more example DO YOU KNOW THE CONTENTS OF THE CAR YOU ARE DRIVING AND THEIR ORIGIN HELL EVEN MERE CAR MANUFACTURING COMPANIES GIVE CONTRACTS TO COMPANIES WHICH SPECIALIZE IN THAT AREA SPEAK ABT FIGHTER AIRCRAFT

the advantages of the above process are
1 u save time and manpower and manhours
2 u get the best stuff available in the market

why do not automobile companies manufacture their own tyres ,brakes headlamps,seats ,microprocessors ,displays.most of them have thair own engines and yes our engine is failed only in providing the required thrust not in reliability.we accept that ,even the Chinese couldn't build their own engine when their project on j-10 began before 1979 .

 

[Myth_buster_1]

"The LCA has indigenous content of more than 70 percent."

care to tell us which 70% of the content are indian? lol what a lier this DR is.

‘‘An aircraft has three major components. An engine, airframe and avionics. The GE-F 404 engine is American, most avionics like radars, INGPS, electronic warfare equipment, radar altometre, the fly-by-wire system, ground-mapping system and other pilot-support system are all imported from Israel, France and Sweden. Even the airframe is not entirely Indian. The composite wings have been imported from Italy.

and quickly tell me what all this 70% is all about or are you all fanboys gonna blindly swallow what ever info DRDO throw at you guys!

Tejas crosses a milestone

Ravi Sharma

BANGALORE: In a milestone, a Light Combat Aircraft (LCA) Tejas took off from here and for the first time dropped live stores (bombs) at a firing range.

The dropping of two 25-pounder bombs, with one striking the target and the other falling within the inner 25 yard circle, was undertaken by Prototype Vehicle-3 of the LCA programme.

The successful dropping of the light, marker bombs will enable the Aeronautical Development Agency (ADA) – designers of the fly-by-wire LCA – to not only prove the working of the aircraft’s flight control software for weapon drops and aiming, but also take forward the LCA’s weaponisation programme.

ADA officials said the flight control system software had to recognise and adjust for the dropping and still maintain the highly unstable flying platform’s handling qualities.

The software had to take into effect the added stores, asymmetric drops, increased sensitivity of the aircraft’s controls and still make sure that the movement of the aircraft’s centre of gravity was still well within limits.

Following this success, the ADA is planning to do as many similar sorties dropping both 25-pounder and 3-kg bombs over the next three days, analyse the results and then prepare for the next stage of the weaponisation programme.

The next stage of weapon trials will see the ADA and the Air Force taking the Tejas to Jamnagar in Gujarat, hopefully by the end of the month. Jamnagar has been chosen as its cross runways will allow the undertaking of both weapon and cross wind trials.

ADA is expected to seek EADS assistance in increasing the"angle of attack" of the LCA

Can some body confirm this news is true? what more EADS would be doing?
What is the present declared angle of attack? why is it missing from Wiki?

BATMAN, there is a tender for consultancy purpose in test program. First Boeing was supposed to do the work but they wanted to sign an agreement that LCA should not be exported. Hence the deal fall through. Now EADS, Dassaut are in race to win the contract. News items suggest that EADS is selected for consultancy.

The angle of attack is something in confusion check this 2005 news item (The LCA puzzle)

But in 2008 news items appeared that AoA is 17 degree and all.

Quite a confusion on this point.

The winner of this contract will be helping the design engineers in widening the flight envelope. Like the recent test of bomb dropping.

listen delusional hindu boy! do i have to prove you the fact that the nazi lost WWII with 2009 articals but i can not post some 60 year old news because they are out dated? are you clearly a retard? The artical that i posted is infact of your rtd Air chief words!

You running around with your usual rants. I am not a hindu. As usual you are far from facts. Don't mess up the things if you don't have any logic behind what ever you are saying. Don't post a 2001 article and run around saying it as FACT. Is it so difficult for you to understand or what?

If you don't have anything sensible to say then keep your mouth shut

 

[aditya_friend]

you yourself say that indian media is crap and then beleive this article

‘‘An aircraft has three major components. An engine, airframe and avionics. The GE-F 404 engine is American, most avionics like radars, INGPS, electronic warfare equipment, radar altometre, the fly-by-wire system, ground-mapping system and other pilot-support system are all imported from Israel, France and Sweden. Even the airframe is not entirely Indian. The composite wings have been imported from Italy."

i also saw an video in which an indian journalist was criticizing jf-17 like hell but it is not that bad.

European jet makers may replace Boeing in Tejas project - Corporate News - livemint.com

European jet makers may replace Boeing in Tejas project

The US plane maker wanted an agreement that American nod would be sought for selling the jet to a third country

K. Raghu

Bangalore: India plans to seek the help of European jet makers such as Dassault Aviation SA and Saab AB to accelerate the development of Tejas, the indigenous light combat aircraft, replacing project consultant Boeing Co., a scientist involved in the project said.

The move comes after the US plane maker insisted that the Aeronautical Development Agency, or ADA, sign a so-called end-user agreement that would require India to seek US permission to export the aircraft to a third country.

Plane dispute: Tejas aircraft in flight. ADA had sought Boeing’s help in hastening the plane’s development for initial certification by 2010, the deadline for achieving the standards set by the Indian Air Force.

US law prohibits the export without its permission of high-technology equipment developed using American consulting partners or components.
“We have already done 99% of the job, the help (we sought) is just for the remaining 1%,” said a senior scientist at ADA, the military plane design agency of the Defence Research and Development Organisation.
The scientist, who did not want to be named because of the sensitive nature of the project, said the agency was yet to decide on a replacement for Boeing.

ADA sought Boeing’s help in speeding up the aircraft development for initial certification by 2010, the deadline for achieving the standards set by the Indian Air Force (IAF). Crucial to this is the Tejas achieving an angle of attack, or AoA, of 24 degree, a measure to prove the agility of the jet at extreme limits of performance.

So far, Tejas has achieved basic standards set by IAF such as reaching 15km in altitude, manoeuvres of 6 g, or six times that of Gravity, speed of Mach 1.6, or 1.6 times the speed of sound, and an AoA of 22 degrees.

Tejas, India’s first homegrown fighter in decades, is a single-engine supersonic fighter that has delta wings and no tail, and uses fly-by-wire technology that enables a pilot to control the plane electronically through on-board computers. “Because of the change in altitude (at 24 degree AoA), it could have an effect on the aircraft characteristics,” the ADA scientist said.
Boeing, which makes military planes such as F-15, F/A-18 and F-22 Raptor, said it continues to be in talks with ADA on the development of Tejas, within the prescriptions of US policy.
“Those requirements are set by the US government, in discussions with the government of India and ADA. So any question on export permissions is best directed to the US government,” said Brian Nelson, spokesman for India at Boeing Integrated Defense Systems, the plane maker’s military wing.
“These issues will (get) ironed out, given the kind of (military and political) engagements between the two countries,” said Ratan Shrivastava, director for aerospace and defence at the India offices of research firm Frost and Sullivan.
Boeing is also in the race for the country’s largest military plane contract of 126 fighter jets that is worth at least Rs42,000 crore, with its F/A-18E/F Super Hornet.
The Hindu reported first on 4 August that Boeing was delaying the Tejas development citing US laws.
This is the second demand in recent times by a US firm that an Indian agency sign the end-user agreement.
On 25 July, Mint reported that the Indian Space Research Organisation would on its own upgrade a semiconductor lab in Chandigarh after International Business Machines Corp. declined, citing concern that the space agency may use the chips designed there to guide rockets and satellites for the military.

ADA to equip Light Combat Aircraft with more powerful engines

New Delhi, Feb 06: With DRDO still looking for partners to develop the indigenous fighter aircraft engine 'Kaveri', Aeronautical Development Agency has decided to equip the Light Combat Aircraft Mark II version with more powerful engines after procuring them from global manufacturers.

"We are looking to procure either the GE-414 from US or European consortium Eurojet's EJ 200 to fly with the LCA Mk II version," Aeronautical Development Agency (ADA) Director P Subrahmanyam told reporters.

LCA's Mk II version is expected to join the IAF in 2014 after the initial two squadrons in Initial Operational Clearance (IOC) configuration are inducted.

DRDO has shortlisted these two engines after going through offers from various global manufacturers.

"Request for Proposals (RFP) is just about to go out and very soon it would be floated," the ADA Director said. The present GE 404-IN 20 engine, he said, was the interim solution as a power-plant for the LCA.

"Since the beginning, we knew that the present engine would be the interim solution as it is adequate for the IOC aircraft. We are looking to get the higher derivatives of GE-414 or EJ-200," he said, adding "we told them (GE and Eurojet) that whatever you have on your drawing boards, we will go ahead with that".

GE-414 is the power-plant for Boeing's F/A-18 E/F and the EJ 200 is fitted on the Eurofighter Typhoon. Both these aircraft are in race for IAF's over USD 10 billion 126 multi-role combat aircraft deal.

On seeking higher derivative of these engines, he said, "If you get a choice between something that is existing and something which is coming in next two to three years and has the highest level of technology, why should we settle down for an existing engine? We will go for what we will get in next three years time."

He said the DRDO wanted the "latest" technology and equipment for the LCA's more lethal version.

Subrahmanyam said apart from the engine technology, ADA will make sure that other equipment and systems on the LCA Mk II are latest. "The open system architecture of the LCA will help us to incorporate and integrate the latest technological advancements in the existing aircraft," he said.

He said ADA has plans of equipping the aircraft with latest avionics and electronic warfare systems so that when it joins the IAF, its technology remains contemporary.

DRDO is hoping to deliver the aircraft to the IAF in IOC configuration by December 2010. IAF will have seven squadrons of the indigenous aircraft of which the first two would be in IOC configuration and the rest would be the Mk II versions.

LM was supposed to design the FBW among numerous other things for LCA. But because of sanctions, they could not.

AFAIK, the FBW for LCA was also tested by LM on another plane.

India has since had to develop all these things inhouse. That article is old, and reflected the view and the progress till that time. A lot of developments have happened since then. You would do well to read up on those.
